The Treadly 2 and Treadly 2 Pro have the auto-alignment feature. The only manual adjustment you will need to do in case of some belt issues would tighten the belt. On rare occasions, if you will need to align the belt manually, please follow the instructions in the video below:
When you should check if your belt is too loose?
- If you are hearing noises from the belt (if it's too loose, the belt could shift too much to one of the sides and create unwanted friction between the belt the frame itself)
- If you are smelling"burning" plastic/rubber (for the same reason)
- If you feel the belt is moving sideways, or not moving as smooth as usual.
How to check if the belt is too loose/Tight?
- Lift the unit from the back and lean it against a wall.
- Hold your fingers firm and press against the belt. The belt ideally should be firm, not too tight or too loose (you should not be able to feel the hard surface under the belt too easily, and at the same time, you should not apply a lot of pressure to feel it. In the video you can see that the left side is too loose, the middle is properly firm, and the right side is too tight:
What to do if the belt is not as firm as it should be?
If the belt is too loose:
Use the L shaped Allan key you received with you Treadly to rotate the screw on the left and right side equally clockwise (rotate it only half a circle, 180 degrees). If you don't rotate it equally, the belt might be unaligned once you walk on the belt.
After you spin the screws once, check again if the belt is loose. If it's still loose, repeat the action until the belt is properly firm to touch.
If the belt is too tight: (could happen if you over tighten it while trying to solve the loosen belt)
loosen it gently by equally rotating counter clockwise (half a spin at a time) the screws on both sides.
After you spin the screws once, check again if the belt is still firm, but not over-tighten. If it's not, repeat the action until the belt is properly firm to touch.
Please note: Start with only 1/2 circle spin as instructed, to avoid over tight or over loose it.
What an overly tight belt can cause:
- Error messages for malfunction of the engine (The engine cannot pull the belt and it will stop)
- Noise from the belt
